THE TECHNOLOGY EXPLAINATION OF BRIGHT ANNEALED STAINLESS STEEL TUBING

Bright annealing equipment is a special equipment which is used to heat the stainless steel tube online to 1050 and then to cool it below 100 rapidly under the protection of hydrogen. The induction heating coil and cooling system are built into the sealed tube. The main feature of the system is the use of non-reusing hydrogen, with a very small flow rate, and only a few liters of pure hydrogen per minute. The gas used is pure hydrogen, which is not dangerous because of its small amount in the gas pipeline.

At the same time, the exhaust gas discharged is burned, which can prevent the hydrogen from diffusing into the surrounding air and thus avoid the accumulation of dangerous concentration in the surrounding space. The heated stainless steel tube is cooled by heat conduction in a special closed cooling tunnel. These characteristics are the reasons why this system only needs a small amount of gas for bright annealing compared with other systems. Gas control system and equipment protection are automatically controlled by PLC. So ensure the high reliability and safety of equipment if power supply using the latest IGBT inverter power supply, its output frequency can be applied to all pipe diameters. This is how bright annealed stainless steel tubing works.
